Cannot read property '.then' of undefined when testing async action creators with redux and react

Question

I\'m trying to write some test using react, redux-mock-store and redux, but I keep getting and error. Maybe because my Promise has not yet been resolved?

Answer 1

Your action creator should return a promise as shown below:

// actions/index.js
import axios from 'axios';

import { FETCH_LISTINGS } from './types';

export function fetchListings() {
  return (dispatch) => {
    return axios.get('/5/index.cfm?event=stream:listings')
    .then(( { data } ) => {
      dispatch({ type: FETCH_LISTINGS, payload: data });
    });
  }
};
